Description

The invention relates to a conductor connection contact with a solder pad for connection to a printed circuit board and a plug contact terminal with a spring clamping element.

The invention further relates to a printed circuit board assembly having a printed circuit board, wherein a conductor terminal contact is soldered with its solder pads on the circuit board.

Printed circuit boards with electrical / electronic components applied thereto have conductor connection contacts for the electrically conductive connection of conductors or for the connection of adjacent printed circuit boards. These are soldered in through-hole mounting or surface mounting on the circuit board and connected to this electrically and mechanically.

DE 200 01 510 U1 shows a connection device for electrical conductors with soldered on a circuit board insulation displacement contact terminals. Such a contact element is designed as a sheet-metal punched / bent part and has two mutually parallel aligned pairs of mouth-like widening in its end region contact cutting for cutting the insulation of an electrical conductor to be clamped on. The contact blades of each pair of contact blades are separated by slots. The two pairs of contact blades are connected to one another via lateral webs. Several such cutting contact elements are band-like connected to each other for common mounting on the circuit board.

EP 0 043 165 A1 shows an insulation displacement contact with two transversely aligned conductor connection regions. The conductor connection areas are each formed by clamping slots on opposite walls, wherein the walls are folded over into a box.

DE 10 2006 052 119 A1 discloses an insulation displacement connection with a first insulation displacement member attached to a first component and a second insulation displacement member attached to a second component. The two insulation displacement elements are inserted into each other in the joining direction and arranged transversely to the joining direction displaceable to each other.

DE 196 17 259 A1 discloses an electrical clamp having an upwardly open insulation displacement contact and other plug contacts disposed in the bottom of the clamp. The clamp is made in one piece from a band-shaped metal strip, wherein the one end of the strip material is divided into a plurality of tongues, one of which stabilizes the shape of the terminal as an anchor end piece and the other as leaf spring end pieces form the insulation displacement contacts , From a bottom surface connecting the insulation displacement contact and the leaf spring end protrude PCB solder pins.

DE 195 12 221 A1 shows an electrical terminal block for printed circuit boards with a aufsteckendem on solder pins bridging rail. The bridging rail is formed as a substantially planar extending flat bridging band having through-slots formed by two resilient tongues punched out of the bridging band.

Proceeding from this, it is the object of the present invention to provide an improved conductor connection contact and an improved printed circuit board arrangement, wherein the conductor connection contact is as compact, easy to handle and stable and ensures a reliable electrical contact.

The object is achieved with the conductor connection contact having the features of claim 1 and the printed circuit board arrangement with such a conductor connection contact with the features of claim 9. Advantageous embodiments are described in the subclaims.

Characterized in that the plug contact terminal is formed on a pad of the conductor terminal contact, which is spaced from the plane of the solder pad, the compliance of necessary clearance and creepage distances can be ensured in a compact design. The connection surface has a plug-in opening and at least one spring-elastic clamping tongue for forming the spring-clamped element. This allows the simple clamping of an electrical conductor which is inserted through the plug-in opening and clamped by means of the resilient clamping tongue on the connection surface of the plug contact terminal.

The connection surface then merges into a foot region, which is in each case connected to a solder connection surface or has a solder connection surface on its side facing away from the connection surface. In this way, the pad is stored stably spaced from the plane of the circuit board by means of the foot sections. The solder pads adjacent to the foot regions thereby ensure that the plug contact terminal is held stable on soldering pads on a printed circuit board when the solder pad contact is soldered. The current flow then goes through the foot areas directly to the solder pad, so that the current-conducting cross sections and paths are optimized.

At the opposite marginal edges of the insertion opening spring-elastic clamping tongues may be bent towards each other pointing. The freely movable ends of the clamping tongues then form clamping edges for clamping an electrical conductor or contact pin inserted into the plug-in opening. In this way, an electrical conductor or contact pin can be clamped very reliably in a very simple construction of the conductor connection contact. The current paths then lead by the shortest route via the clamping tongues and the foot sections to the solder connection surfaces.

At the conductor connection contact can continue to be present an insulation displacement contact connection.

A solder pad can be arranged between a insulation displacement contact connection and a web leading to the connection plane. This has the advantage that the insulation displacement contact connection and the connection surface are connected to one another via the common solder connection surface, wherein the current paths between the insulation displacement contact and plug contact connection are short and the insulation displacement contact connection and the plug contact connection via the common solder connection surface mechanically stabilized.

The insulation displacement contact terminal may have two spaced-apart contact fingers connected together in a common root section. The root section then merges into the foot section or forms the foot section. Thus, it is conceivable that the root section merges into one of the solder connection surfaces. This then leads to a very compact construction of the solder connection contact.

The extension direction of a clamped at the insulation displacement contact terminal jumper in the clamping region on the insulation displacement contact terminal can be aligned transversely to the direction of insertion of the plug contact terminal. The extension direction of the wire bridge at the insulation displacement contact connection in the region of the terminal point, in which a wire bridge is guided to the clamping point between the contact fingers, however, runs in the plugging direction of the plug contact terminal. The plane spanned by contact fingers of the cutting plug connection terminal or a slotted wall for forming the cutting plug contact connection is thus aligned transversely to the plane of the connection surface. By "transverse" is meant an orientation in the angular range of 90 ° +/- 20 ° and preferably 90 ° +/- 5 °.

The extension direction of the jumper clamped onto the insulation displacement contact connection in the clamping region of this insulation displacement contact connection can be in the extension direction of the connection surface or else transversely to the extension direction of the connection surface. It is also conceivable that it is aligned obliquely to the extension direction of the connection surface.

The printed circuit board assembly has a printed circuit board in which such a conductor connection contact is soldered to its solder pads on the printed circuit board. The printed circuit board then has a conductor lead-through opening below the plug-in opening, so that an electrical conductor can be inserted through the conductor lead-through opening into the plug-in opening and clamped to the plug-in contact socket. This allows a very compact connection of an electrical conductor to the circuit board with a plug-in direction perpendicular to the circuit board.

The pad of the conductor connection contact may extend parallel to the plane of the circuit board. A section of the conductor connection contact having the insulation displacement contact connection then projects from the plane of the circuit board.

From the pad, a material tab may be spaced apart from one of the solder pads, e.g. protrude in the direction of an insulation displacement contact connection. This enlarges the pad adjacent to the plug contact. This material flap (also referred to as flap) serves to provide an enlarged suction surface for automated handling and assembly of the conductor connection contacts.

The clamping spring tongues can have a bend or a bend in an area located upstream of the respective clamping edge. As a result, the mutually bent-out clamping tongues are aligned at a greater angle to one another in the regions adjoining the connection surface than in the region adjoining the clamping edge. Due to the kink or the bend adjacent to the clamping edges surfaces of the opposing clamping tongues are thus arranged at a more acute angle to each other. These additional bends lead to a reduction of the insertion forces and allow the release of a connected conductor by turning and pulling the clamped conductor.

The circuit board assembly may have a plurality of circuit boards disposed adjacent to one another. The conductor connection contacts are then arranged at opposite edge regions of the printed circuit board diagonally offset from one another. Thus, the adjacent circuit boards can be electrically connected to each other by means of wire bridges, which are located between the extending opposite conductor connection contacts. Due to the diagonally offset arrangement of the conductor connection contacts, the wire bridges are then guided over several bends, so that a sufficient tolerance compensation of thermal expansions is ensured. Due to the diagonally offset arrangement of the conductor connection contacts, a point or mirror-symmetrical arrangement of the conductor connection contacts on a printed circuit board is also possible. For example, conductor connection contacts can be arranged point-symmetrically diagonally offset from one another at mutually opposite edge regions of a printed circuit board.

A wire bridge in the sense of the present invention is understood to mean an electrical lead which can be clamped in the insulation displacement contact connection, in particular a non-insulated piece of wire, an insulated electrical conductor (rigid or flexible) or also a conductor piece with e.g. rectangular cross-section.

For the purposes of the present invention, the indefinite term "a" is not to be understood as a number word, but in the sense of "at least one".

The invention will be explained in more detail with reference to embodiments with the accompanying drawings. Show it:

1a) lets a perspective view of a first embodiment of a conductor connection contact 1 recognize, which is integrally formed from a piece of sheet material as a punched and bent part. The conductor connection contact 1 has a insulation displacement contact connection 2 at one end. This insulation displacement contact connection 2 is made of two contact fingers 3 formed, which are parallel to each other with an intermediate clamping slot 4 aligned on a common plane and over a common root area 5 connected to each other. The free end portions of the contact fingers 3 are to the root area 5 towards a funnel-shaped inlet, for example through an inlet bevel 6 designed so that the insertion of a wire bridge in the clamping slot 4 is relieved.

The mutually facing inner edges 7 the contact finger 3 clamp by the spring force of contact fingers 3 and the adjacent root section 5 a wire bridge between them. They are at least as far as formed as cutting contacts that the contact fingers 3 dig into the surface of an inserted wire bridge. But they can also be sharp-edged to a Isolierstoffmantel a wire bridge, for example. An insulated rigid or flexible electrical conductor, when inserted into the insulation displacement contact 2 cut open to expose in this way the electrically conductive part of the wire bridge and electrically conductive with the contact fingers 3 to contact.

It also becomes clear that the conductor connection contact 1 a plug contact connection 8th on a connection surface 9 having. This interface 9 has a plug-in opening 10 as well as elastic clamping tongues 11 that is from the plane of the pad 9 and from the plug-in opening 10 off and on each other. The clamping tongues 11 are made of the sheet material of the pad 9 cut out or punched out and protrude from opposite edges of the plug opening 10 from. The plug-in opening 10 is then still by opposing side bars 12 limited.

Furthermore, the conductor connection contact 1 two solder pads 13a . 13b , Visible is that the connection surface 9 on a plane above the through the solder pads 13a . 13b spanned level lies. Between the connection surface 9 and the solder pads 13a . 13b are foot sections 14 provided, which adhere to the connection surface 9 connect and to a respective solder pad 13a . 13b to lead. These foot sections 14 are in the illustrated embodiment as of the pad 9 formed folded webs. These are approximately perpendicular to the pad 9 bent.

The solder pads 13a . 13b can be at the end of the foot sections 14 be formed or as in the case of the solder pad 13a after another bend from the foot section 14 in a solder pad 13a pass.

It becomes clear that the horizontal solder pad 13a in the insulation displacement contact connection 2 or its root section 5 passes. This root section 5 with the adjoining contact fingers 3 extends approximately parallel to the foot section 14 so that the insulation displacement contact connection 2 and the foot section 14 approximately perpendicular to the insulation displacement contact terminal 2 with the foot section 14 connecting solder pad 13a stand. The connection surface 9 however, lies on a plane transverse to the plane of extent of the insulation displacement contact terminal 2 lies. The insulation displacement contact connection 2 is thus aligned on a plane perpendicular to the plane of the pad 9 stands. It is also conceivable, however, that the plane of the connection surface 9 at an angle of 90 ° +/- 45 ° to the plane of the insulation displacement contact connection 2 stands.

Through the two foot sections 14 at the opposite ends of the pad 9 can the conductor connection contact 1 be soldered stable on a circuit board. With the help of the transition from the first solder pad 13a to the protruding insulation displacement contact connection 2 This is also stable connected to a printed circuit board with short current paths.

1b) shows a comparison with the embodiment of 1a) slightly modified version of the conductor connection contact 1 , Essentially, reference may be made to what has been said before. In addition is at the connection surface 9 at a distance from the horizontal solder pad 13a a material lobe 3 provided by the in the foot section 14 Transitioning curve is cut free and the flat surface of the pad 9 enlarged in the area of the bend. This is the suction surface for the automatic handling and assembly of the conductor connection contact 1 increased. In the illustrated embodiment, the material flap 33 on the side of the insulation displacement contact connection 2 provided and extends in the direction of this insulation displacement contact terminal 2 , It is also conceivable, however, that such a material lable 33 on the opposite side at a distance to the solder pad 13b) is present or that such material tabs are provided on both sides. This also depends on the position of the plug hole 10 at the connection surface 9 concretely.

Furthermore, it can be seen that the solder pad 13b) on the right side of the foot section 14 goes over in a bend and provides a surface Auflagerung. This solder pad 13b) will not be like in 1a) only through the lower edge of the foot section 14 formed, but by a from the foot section 14 transverse to a bend away extending surface portion.

Also the insulation displacement contact connection 2 is compared to the embodiment of 1a) something modified. It becomes clear that the outer edges of the contact fingers 3 , each one the clamping slot 4 opposite, are concave towards the clamping slot. This is the width of the insulation displacement contact connection 2 in the region of the contact slot less than in the region of the inlet slopes 6 , In this way, the spring force of the contact fingers 3 be improved.

2a) leaves a side view of the conductor connection contact 1 out 1a) detect. Hereby it becomes again clear that the connecting surface 9 from the plane of the solder pads 13a . 13b is spaced, what through the foot areas 14 is reached. It can also be seen that the insulation displacement contact connection 2 on a plane transverse to the plane of the pad 9 standing level.

The clamping tongues 11 the spring clamping element facing each other from the plane of the pad 9 and from the plane of the solder pads 13a . 13b turned away pointing away. The freely movable ends of the spring-loaded clamping tongues 11 have clamping edges 15 to form a plug contact to one in the underlying insertion opening 10 in the insertion direction S plugged electrical conductor or pin to connect between them and thus to contact electrically conductive.

2 B) leaves a side view of the modified conductor connection contact 1 out 1b) detect. Here it becomes clear that the material lobe 33 at a distance to the solder pad 13a at the level of the interface 9 in the direction of the insulation displacement contact connection 2 extends so as to increase the suction area for a handling machine.

It is clear that the right solder pad 13b) not just from the bottom edge of the foot section 4 but from one of the foot section 4 away extending surface portion is formed.

It is still recognizable that the contact fingers 3 of the cutting clamp connection tapering towards the free end in terms of their width. That is, the material thickness of the contact fingers 3 decreases towards its free end.

3 Leaves a front view on the conductor connection contact 1 out 1a and 2a detect. It becomes clear that the contact fingers 3 leaving an intermediate clamping slot 4 are formed from the sheet material and in a curvature in a common root area 5 pass. The contact fingers 3 taper towards the free end, the inner edges there on an inclined surface 6 form an introduction funnel.

The insulation displacement contact connection 2 is thus formed in the manner of a fork contact to one in the clamping slot 4 inserted jumper in the form of a non-insulated, round in cross-section rod, an insulated rigid or flexible electrical conductor or a cross-sectionally round, rectangular or otherwise suitable power rail.

4 leaves a top view of the conductor connection contact 1 out 1a detect. It becomes clear that the connection surface 9 a plug-in opening 10 has, from its opposite edge regions of the resilient clamping tongues 11 protrude to form a spring clamping element. An electrical conductor can thus from the bottom through the plug opening 10 inserted through and with the spring-elastic clamping tongues 11 be clamped.

The insulation displacement contact connection 2 on the left side of the conductor connection contact 1 however, extends on a plane perpendicular to the plane of the conductor pad 9 lies. The contact fingers 3 of insulation displacement contact terminal 2 lie on a plane that is transverse to the longitudinal direction of the conductor connection contact 1 and its pad 9 is. The longitudinal extension direction is the direction of the insulation displacement contact terminal 2 to the plug contact connection 8th ,

5 leaves a second embodiment of a conductor connection contact 1 detect. This is constructed in principle similar to the first embodiment. Only the insulation displacement contact connection 2 is opposite to the extension direction of the conductor connection contact 1 twisted. It can be seen that the contact fingers 3 now lie on a common plane, which is transverse to the plane of the pad 9 and in the longitudinal direction of the pad 9 , ie to the plug contact connection 8th extends. Thus, the direction of extension is one of the insulation displacement contact connection 2 clamped wire bridge in the clamping area transverse to the longitudinal direction of the conductor connection contact 1 while the extension direction of the cutting-to-terminal contact terminal 2 in the first embodiment in the longitudinal extension direction of the conductor connection contact 1 is aligned.

The connection surface 9 does not necessarily have to be a flat surface, as shown. It can also be a curved surface, which is followed by curved or straight foot sections 14 passes. It is also conceivable, however, a cross-sectional pointed roof-shaped design of the connection surface 9 with inclined to the plane of the circuit board foot sections 9 ,

6a) shows a perspective cutaway view of a printed circuit board assembly 16 detect. This circuit board arrangement 16 has at least two adjacent juxtaposed circuit boards 17a . 17b on each of which at least one conductor connection contact 1 is soldered. Visible is that the connection surface 9 with the plug contact connection 8th with the help of the opposite foot sections 14 at the level of the circuit board 17a . 17b each superimposed or from the plane of the circuit board 17a . 17b is spaced. Furthermore, it becomes clear that below the plug opening 10 of the plug contact connection 8th a conductor passage opening 18 is introduced into the circuit board. The conductor lead-through opening 18 is on the plug-in opening 10 aligned so that their center of gravity preferably on a common perpendicular of the circuit board 17b stands, so that an electrical conductor through the conductor opening 18 in the plug-in opening 10 can be guided to there at the plug contact connection 8th to be clamped.

It also becomes clear that the conductor connection contacts 1 the neighboring circuit boards 17a . 17b , which are adjacent to each other, diagonally offset and are arranged rotated relative to each other. As a result, the insulation displacement contact terminals 2 the two adjacently arranged conductor connection contacts 1 along the length of the conductor connection contacts 1 staggered to each other. A wire bridge 19 can thus with its opposite free end portions 20a . 20b each to an associated insulation displacement contact connection 2 be clamped. The clamping direction and thus the extension direction of these end portions 20a . 20b the wire bridge 19 runs transversely to the plane of the insulation displacement contact connection 2 in the main extension direction of the conductor connection contacts 1 and the adjacent edge of the respective circuit board 17a . 17b , From the opposite end portions 20a . 20b the wire bridge 19 is each a common main section 21 bent, which is transverse to the longitudinal direction of the conductor connection contacts 1 and thus also transversely to the extension direction of the gap between the two circuit boards 17a . 17b extends.

In case of using a conductor connection contact 1 according to the second embodiment in 5 would the wire bridge 19 then simply be turned 90 ° so that the main section 21 in the extension direction of the conductor connection contacts 1 and the adjacent marginal edges or the space between the circuit boards 17a . 17b extends. The end sections 20a . 20b would then in their extension direction transverse to the longitudinal direction of the conductor connection contacts 1 to the respective insulation displacement contact connection 2 be clamped.

6b) shows one compared to 6a) slightly modified perspective cutaway view of a printed circuit board assembly 16 in which the insulation displacement contact connections 2 aligned so that the from the contact fingers 3 spanned levels face each other, ie assign each other. These planes are aligned parallel to each other. Therefore, they are in the clamping slots 4 inserted end sections 20a . 20b each on the opposite circuit board 17a . 17b aligned pointing. Instead of a straight wire bridge, however, one through a loop-like section 34 coiled embodiment used. This is a tolerance compensation in a positional shift of the circuit board assembly 16 ensured.

7a) leaves the opposite side of the circuit board 17b with an adjoining further circuit board 17c the circuit board assembly 16 detect. These are the last circuit boards 17b . 17c a matrix-like juxtaposed number of circuit boards 17a . 17b . 17c , ... There are now on their longitudinal edge adjacent PCBs 17b . 17c electrically connected to each other. For this purpose, in turn, a wire bridge is provided, which is designed as a non-curved, straight rod or electrical conductor. As the extension direction of the to the insulation displacement contact terminals 2 clamped wire bridge 19 in the region of the respective terminal point of the two conductor connection contacts to be connected to one another 1 aligned in the direction of arrangement, the free end sections 20a . 20b without further bending of the wire bridge 19 transverse to the plane of the insulation displacement contact terminals 2 be clamped to it.

It is also recognizable that the printed circuit boards 17a . 17b . 17c electrical or electronic components 22 wear, in particular light emitting diodes. This circuit board arrangement 16 can thus be used for a lamp. The circuit boards 17a . 17b . 17c carry printed conductors 23 at the solder pads 13a . 13b with a respective conductor connection contact 1 are soldered. This allows electrical energy via the conductor connection contacts 1 the electrical / electronic components to be supplied 22 be supplied.

7b) shows a modified embodiment of a printed circuit board assembly 16 in which the interconnected insulation displacement contact terminals 2 are aligned so that the clamping slots 4 not as in the embodiment 7a) aligned facing each other. Therefore, the end portions extend 20a . 20b the wire bridge 19 approximately parallel to one another in the same main extension direction. The two end sections 20a . 20b are through a crossbar 35 connected with each other. The wire bridge 19 is designed in the manner of a U-shaped element.

8th shows a perspective cutaway view of the circuit board assembly 16 detect in an area where electrical conductors 24 each through a conductor passage opening 18 in the circuit board and the overlying plug hole 10 of the conductor connection contact 1 are guided. The free stripped end of an electrical conductor 24 is then at the clamping edges of the resilient clamping tongues 11 clamped and contacted there electrically conductive and mechanically held. This can be a voltage potential to the circuit board assembly 16 be applied to the electrical / electronic components 22 to provide electrical power. In this case, the insulation displacement contact terminals 2 as shown not occupied when the electrical / electronic components 22 and their circuit boards 17a . 17b . 17c . 17d . 17e are connected in series. In a parallel circuit, however, it is conceivable that the insulation displacement contact terminals 2 a wire bridge 19 wear to the electrical power not just over the tracks 23 to the opposite conductor terminal 1 same circuit board 17a . 17b . 17c . 17d . 17e but directly to an adjacent circuit board 17a . 17b . 17c . 17d . 17e ,

9 leaves a sectional view of the circuit board assembly 16 out 8th with attached electrical conductor 24 detect. It becomes clear that the circuit board 17d on a support element 25 is superimposed. This carrier element 25 can be, for example, a sheet metal housing a lamp. In the carrier element 25 is aligned with the conductor opening 18 the circuit board 17d a passage opening 26 brought in, with a grommet 27 is closed. The electrical conductor 24 is then through the opening of the grommet 27 passed, as shown at a plug contact connection 8th to be contacted electrically conductive.

Opposite the carrier element 25 is a lens element 28 eg made of transparent plastic on the support element 25 put on so as to cover the lighting arrangement and of the electronic components 22 to emit light emitted in the form of light emitting diodes as uniformly as possible or in a focused manner. Visible is that of the lens element 28 Stege 29 in the area of insulation displacement contact connections 2 protrude. These bridges 29 Take eg a insulation displacement contact connection 2 on both sides in a groove of a bridge 29 on. In the footbridge 29 is then a slot in the region of the gap between the clamping fingers 3 present to a wire bridge 19 through the footbridge 29 pass and at the associated insulation displacement contact terminal 2 anzuklemmen.

The wire bridges can be used for the assembly 19 in these bars 29 are inserted, so that by placing the support element 25 with the pre-assembled printed circuit boards 17a . 17b . 17c . 17d on the lens element 28 the wire bridge 19 in the clamping slots 4 the insulation displacement contact terminals 2 be introduced.

Thus, the creepage distances and creepage distances are increased and it becomes a support for the carrier element 28 created.

10 lets a perspective view of a section of a light assembly 30 with the carrier element 25 out 9 and built therein strip-shaped printed circuit boards 17a . 17b . 17c . 17d detect. It becomes clear that every circuit board 17a . 17b . 17c . 17d at its opposite ends adjacent to the narrow edges of the conductor connection contacts 1 wearing. These are arranged point symmetrical to each other, so that the insulation displacement contact terminals 2 such a pair of conductor connection contacts 1 each pointing to the other longitudinal edge or adjacent to the other longitudinal edge 31a . 31b are arranged.

It also becomes clear that electrical conductors 24 from the underside of the carrier element 25 transverse to the plane of the circuit boards 17d . 17c are introduced to the plug contact terminals of this conductor connection contacts 1 to be clamped.

At the front end is the support element 25 with an end cap 32 completed on the profile of the support element 25 is plugged.

11 shows a perspective view of another embodiment of a conductor connection contact 1 , This differs from the above-described conductor connection contacts 1 in that no insulation displacement contact connection 2 for clamping another electrical conductor or a wire bridge is present. These conductor connection contacts 1 are in particular for the end connections of a lighting arrangement 30 intended to be clamped to the power supply / discharge lines.

For the further structure can be made to the description of the embodiment of 1b) to get expelled. It is also conceivable that in 1a) illustrated embodiment or other variants without insulation displacement contact connection 2 are executed.

12 leaves a modified embodiment of a conductor terminal contact 1 recognize where the clamping tongues 11 with another bend 36 or a kink. This is the clamping tongues 11 in their area, attached to the interface 9 adjacent, arranged at a greater angle to each other (ie, with a shallower angle), as in which to the clamping edges 15 adjacent area. Adjacent to the clamping edges 15 adjacent section of the clamping tongues 11 is thus exhibited steeper than the one in the connection surface 9 transitional area of the clamping tongues 11 , As a result, the insertion forces for the insertion of an electrical conductor are reduced and it becomes possible to loosen a connected electrical conductor by turning and pulling.

This embodiment of the clamping tongues 11 is in 13 based on the page presentation even clearer. In the illustrated embodiment, it is provided that the at the clamping edges 15 adjacent sections of the clamping tongues 11 are arranged at an acute angle in the rest position with no electrical conductor plugged in while the contact surface 9 subsequent sections of the clamping tongues 11 are aligned at an obtuse angle to each other. This does not change even when pinching an electrical conductor, since the further raising of the clamping tongues 11 although reducing both angles, the relationship between obtuse angle and acute angle is still maintained.

14 lets out a perspective view of the modified embodiment 12 and 13 detect. These bends 36 can in principle also other configurations of the conductor connection contacts 1 , in particular the conductor connection contacts 1 out 1a) and 11 be provided equally. It is again clearly visible that the clamping tongues facing each other obliquely from the connection surface 9 are bent out. Through the bends 26 or a kink becomes the angle between the opposing portions of the clamping tongues 11 reduced. As a result, the insertion forces for a through the plug opening 10 reduced electrical conductor and the conductor can by turning and pulling from the connector 8th be removed.
